Abstract

A pulsed source of hard X rays for high-speed radiography is described. The source is composed of a line pulse transformer, which is discharged into an accelerating tube with a vacuum diode, producing a high-voltage pulse across the tube with an amplitude of up to 750 kV. The effective energy of X-ray quanta, determined by attenuation in a 5-mm-thick steel plate, is 125 keV. The X-ray dose at a distance of 1 m from the anode is 10 and 15 mR at a 40- and 60-ns full width at half-maximum of the X-ray pulse, respectively. The diameter of the X-ray emitting spot is <2 mm. Photographic images of a steel step wedge 5-15 mm thick and steel beads ≥0.5 mm in diameter have been obtained.
